We recently reviewed one of our favorite keyboard solutions for the iPad, Logitech’s Ultrathin iPad Keyboard Cover. However, we have seen a few new competitors since then. Most notably: ZAGG’s new KeysPRO line, which we were able to get our hands on at IFA last month. The ZAGGKeys PRO caught our eye with its backlit keys, rugged build quality and battery life of up to three weeks at eight hours a day. It has potential to become the go-to iPad keyboard when it goes on sale at the end of the month (full review on the way), but one keyboard recently released already has it beat, at the very least, on battery life…

Logitech’s new Solar Keyboard Folio for iPad 2 and 3 comes with one impressive claim: the ability to type for two hours a day for two years on a full charge…even in the dark. That claim combined with a solid Logitech keyboard similar to what we’re used to from the company’s past iPad products, we essentially get solar power and a folio-style case added to the Ultrathin Keyboard cover for an extra $30.

I have had long enough since its release to put it to the test and have a couple of thoughts:

Amazon offers the Logitech Wireless Solar Keyboard K760 for Mac/iPad/iPhone (920-003884) for just $59.99 with free shipping (Amazon Store link). That’s the first time we’ve seen this keyboard marked down from its $80 retail price. The Logitech Wireless Solar Keyboard K760 keyboard charges by sunlight/lamplight and can run for 3 months in total darkness. Users can also immediately switch between iPhone, iPad and Mac (or any 3 devices) with dedicated function keys.

Logitech first started producing solar wireless keyboards for PCs earlier this year but didn’t make a Mac version until a few months ago. The PC version got incredibly solid reviews at Amazon so I thought this would be a good pick up for my Mac workstation when it was released. As a veteran of Apple’s original Wireless Keyboard, I was sick of dealing with battery and connectivity issues plus I wanted the full layout with numeric keypad, extra function keys extra and full arrows. I’ve been using it almost exclusively for the past three months.

First, I’ll say that the solar panels make the footprint about 25% bigger than a standard full Apple keyboard. That can be a hassle if you are cramped for space at your desk. On the other hand, the keyboard feels a bit more solid, perhaps because of the increased size and weight. Keystrokes are very similar feel to Apple’s standard keyboards and spacing and layout are all but identical. Logitech adds a power switch and battery tester at the top right.

I got the piano black version because it matches my monitor and my Logitech Mouse (which also works with this USB dongle) but there are 5 colors to choose from. I imagine the standard “silver” will be the most popular.

As far as the solar is concerned, I never had a single problem with charging or connection. I have a florescent lit basement office and a workspace with natural light from a shaded back yard and both kept the keyboard charged at all times. The keyboard usually sits in front of a large 30″ monitor, so that probably helps. But from reviews I’ve read, almost no one has a problem keeping this charged with normal office lighting so I don’t think this is a concern.

Today, Logitech announced that a Mac version is on the way. As a bonus, it is available in 5 colors including black, white and 3 different admittedly ugly pastels. Interestingly, Logitech is selling it for $20 less than the list price of the $79.99 PC version at $59.99. So much for the Mac Tax?

Besides the pastels, this product looks like a winner. Sign us up.

Additionally, Logitech launched a $50 back mounted iPad speaker earlier this week. It has batteries which last about as long as an iPad and also charges via USB. I’m not immediately sure if I like this idea or more importantly, the implementation but, there it is:
